Patent CA-2202119-A1 (CA)
Title: Five-piece open container with locking arrangement
Inventor: LESSARD CLAUDE
IPC: B65D6/26
Filed: 1997-04-08
Abstract: A five-piece open container comprises a bottom piece formed of plastics material and four side pieces also formed of plastics material and pivotally mounted to the bottom piece so that the side pieces may be pivotally moved between an erected position and a non-erected position. In the upper corner of each piece are provided parts which are integral with the side pieces and which enable the side pieces to be maintained in an erected inter-engagement. One of the integral parts ensures a securing arrangement when the side pieces are in the erected position, but it may be manually flexed outwardly from inside the container to enable the disengagement of the side pieces from one another so that they may be moved into a non-erected position.
Patent CA-2202201-A1 (CA)
Title: Communication apparatus
Inventor: HAYASHI MOTOHIKO
IPC: H04N1/44
Filed: 1997-04-09
Abstract: An object of the invention is to provide a communication apparatus which performs a maintenance operation in a short period of time, without using a communication apparatus which includes a special communication protocol on a maintenance side. In a facsimile machine, upon receipt of a DTMF signal on a communication line, the DTMF signal is supplied to a modem through a relay and a transformer, so that the modem converts the received DTMF signal into a code signal such as 1 to 0, * and # and supplies the code signal to a CPU through a data bus which is formed by a gate array and a main gate array. The CPU stores the code in a temporary storage RAM, digit by digit. In the meantime, when it is determined that the code signal is "96#", from a RAM, the CPU reads a functional parameter associated with the number of a soft switch which is temporarily stored in the RAM. Among data regarding the soft switch, the CPU changes data which are associated with a data number which is temporarily stored in the RAM into a changed value which is also temporarily stored in the RAM and writes the changed value in the RAM again.

Patent CA-2205603-A1 (CA)
Title: Fault monitoring
Inventor: O'MALLEY MICHAEL
IPC: H04L12/26
Filed: 1995-12-22
Abstract: Faults occurring in a telecommunications system (21) are monitored identifying their time of onset and reporting them to an operator through an interface (16) if they have not cleared within a predetermined interval. Transient faults, which do clear within that interval, are not reported directly, but only if such faults occur more frequently than a predetermined rate. This is determined by establishing a scan interval, and an analysis period equal to a plurality of scan intervals, monitoring the system (21) continuously for the occurrences of faults, and storing their times of occurrence in a store (8).  At the end of each scan interval, the number of occurrences of the fault during the analysis period which ends at the end of the scan interval are counted by a counter (11). If the number of occurrences of the fault in the analysis period is equal to or greater than a threshold value selected by user input (16), an alarm indicator (17) is activated. This allows isolated transient faults to be disregarded, allowing the user to concentrate on recurrent intermittent faults.

Abstract: A shingle (20) is provided having a headlap section (32) and a buttlap section (34) with at least one portion of the buttlap section having a relatively uniform color and/or value and an adjacent portion of the buttlap section having a value gradation from light to dark. A plurality of horizontal striations (52, 54, 56) with transition stripes (152, 154) disposed between adjacent horizontal striations may be used to establish the desired value gradation. An illusion of depth or shingle thickness is created on the portion of the buttlap section having the value gradation. The buttlap section defines in part the exposed weather surface (42) of the associated shingle. The relatively uniform color and/or value portions may be formed on tabs or dragon teeth (36) and the value gradation formed on a backer sheet (50) disposed beneath the tabs. Openings (38) between tabs expose the enhanced value gradation to view.

Title: Fastener and method of operation thereof for installing a thin layer of material at an adjustable distance from a support
Inventor: GUELCK VOLKER
IPC: F16B43/00
Filed: 1997-11-21
Abstract: A fastener has a screw with an anchor located thereon, the anchor being spaced apart from the head. The anchor has a cut-away portion with a leading edge and a trailing edge of the cut-away portion angling downward. The leading edge angles downward a further distance than the trailing edge.  The anchor is spaced apart from the head by a distance corresponding to a thickness of a layer of material to be affixed to a support by an adjustable distance.  The layer of material has a small opening therein to accommodate the screw.  When the screw is inserted through the opening and into the support, the anchor turns through the opening, even though the opening is smaller than the anchor so that the material is located between the anchor and the head.  The screw can then be turned further into the support or further out of the support to adjust the distance between the material and the support in order to align the material as desired.

Title: Timing recovery and frame synchronization in a cellular communications system
Inventor: LI YONG
IPC: H04L27/22
Filed: 1996-06-26
Abstract: Timing recovery, with or without frame synchronization, in a cellular TDMA  communications system is carried out by a method comprising estimating indirect variables, which embody sampling delay information, of a linear complex vector using a maximum likelihood criterion, and recovering the sampling delay from the estimated indirect variables. For recovering the sampling delay, an optimal procedure and three sub-optimal, but computationally simpler, procedures are described, along with their physical implementations. For frame synchronization, the timing recovery sampling delay is supplemented by a number of sample spacings determined by a maximum of signal amplitudes of a plurality of samples, calculated from the estimated indirect variables and the timing recovery sampling delay.

Filed: 1998-05-20
Abstract: A waveguide element is capable of realizing acute waveguide discontinuity,  such as a right angle bending, (L-shaped bending) or branching (T-shaped branching).  Two single mode waveguides having the identical cross-sectional structure form a waveguide discontinuity where center axes thereof extending in the longitudinal direction intersect with each other at an angle .theta.
